Steel Fire Door
View Products +Fire Rated Doors
LHSH manufactures commercial steel fire doors for fire compartmentation, protected escape routes, equipment rooms, industrial facilities and other building areas where reliable fire and smoke control is required. Our steel fire door range includes single-leaf, double-leaf and unequal-leaf configurations for different opening widths, traffic requirements and architectural layouts.
A complete steel fire door and frame solution can be engineered according to project drawings, opening dimensions, required fire performance, wall conditions and hardware requirements. Door size, frame configuration, surface finish, vision panel and hardware preparation can be coordinated before production to reduce modification work during installation.
Fire Compartmentation
● Helps restrict the spread of fire and smoke between designated building zones when correctly specified and installed as part of the fire-rated opening system.
Durable Steel Construction
● Suitable for high-traffic commercial and industrial environments where strength, dimensional stability and long-term service performance are important.
Project-Based Configuration
● Single, double and unequal-leaf configurations can be selected according to opening width, evacuation requirements and daily traffic conditions.
Door and Frame Coordination
● Door leaf, steel frame, hardware preparation and project dimensions can be coordinated before manufacturing to improve installation compatibility.
Commercial projects rarely rely on one standard opening throughout an entire building. LHSH can coordinate door configurations with architectural drawings and project requirements so that multiple openings can be managed within one fire door package.
Door Size and Configuration
● Project-specific width and height based on approved opening schedules.
● Single-leaf, double-leaf and unequal-leaf configurations.
● Opening direction coordinated with architectural and evacuation requirements.
Vision Panels
● Vision panels can be incorporated where visibility between spaces is required.
● Glass and glazing configuration must be selected according to the applicable fire-rating and project requirements.
Surface Finish
● Surface treatment and color can be coordinated with the architectural finish schedule.
● Finish selection should consider interior or exterior location, environmental exposure and aesthetic requirements.
Hardware Preparation
● Hinges
● Locks and handles
● Door closers
● Exit or panic hardware where specified
● Other project-specific hardware subject to technical review

What is a commercial steel fire door?
A commercial steel fire door is a steel door assembly designed for use in a fire-rated opening to help limit the spread of fire and smoke between building compartments. Its required performance depends on the applicable building code, certification and project specification.
Can LHSH supply the steel fire door and frame together?
Yes. LHSH can coordinate the steel fire door and frame as part of the project opening solution, including dimensions and hardware preparation according to confirmed project requirements.
Are custom steel fire door sizes available?
Project-specific dimensions can be reviewed by LHSH. Buyers should provide the structural opening dimensions, wall thickness, required clear opening and door schedule for technical confirmation.
Can steel fire doors include vision panels?
Vision-panel configurations are available for suitable projects. The glass, panel dimensions and glazing system need to comply with the required fire-performance specification for the complete opening.
Should I choose a single or double steel fire door?
Single-leaf doors are commonly used for standard pedestrian openings. Double-leaf doors are more suitable for wider openings, high-traffic routes and locations where equipment or large items need to pass through the opening.
What information is required for a steel fire door quotation?
Provide the required fire performance, opening dimensions, wall thickness, door configuration, swing direction, finish, vision-panel requirement, hardware schedule, quantity and delivery destination. Project drawings are recommended for multi-door projects.
